A Comparative Study of Ultrasound-Guided Quadratus Lumborum Block and Transversus Abdominis Plane Block for Postoperative Analgesia Following Total Abdominal Hysterectomy

Abstract

Background: Total abdominal hysterectomy (TAH) results in remarkable postoperative pain. Truncal nerve blocks like the quadratus lumborum (QL) block and transversus abdominis plane (TAP) block are described to combat this pain. The aim of the present study was to compare the effectiveness of the QL block with the TAP block in terms of numeric rating scale (NRS) scores as the primary outcome for postoperative pain in TAH. The secondary outcome was time of the first analgesic demand, total analgesic demands required in 24 hr, and patient satisfaction level.
